Abstract
The present invention relates to a radiator used for heating and residual heat utilization. A vacuum phase transition system is formed inside the radiator whose lower part is provided with an isolated pipe. The convention that the radiator is filled with a heating medium when the heating medium flows across is altered, the corrosion and the scale formation of an inner wall are thoroughly eliminated, and the cold resisting property is good. Internal pressure can be designed to work in a certain range which is lower than or equal to the pressure of a heating system, and a thin wall has the advantages of long service time, high efficiency, pressure resistance, anti-freezing property, corrosion resistance and anti-scale formation. The radiator can be generally used in various heat pipe networks, and heat can be radiated by a single heat pipe or residual heat air and the compression heat transmission of a heat pump. An exhaust heat boiler or a system by which the heat is used can be formed by the radiator combined with the evaporation zone of a separate type heat pipe, the exhaust heat boiler or the system is in the mode of long distance transmission, and steel products can be effectively saved.
Description
The invention belongs to radiator.
There is the following deficiency to some extent in present various radiator:
1, the heat radiation wall is thicker, and thermal resistance is big, steel consumption is many, and fouling and corrosion are serious, and voltage endurance capability is poor, leaks vapour and leaks more general.
2, existing heat pipe and vaccum phase conversion heat exchanger still can not generally be used for various heat transfer cooling system heat supply networks.
The objective of the invention is to propose a kind of neotectonics heat sink technology scheme, reduce rolled steel dosage, improve radiator resistant to rust ability, improve the thermal efficiency, and wider range of application is arranged.
Content of the present invention is the pressure change-vacuum-phase change radiator that the thermal medium of a kind of heating and UTILIZATION OF VESIDUAL HEAT IN and internal pressure and heating system separate, good by the air-tightness that allows to be used in vacuum range, inhale the column comb that can bear high vacuum negative pressure and thermal expansion normal pressure of the few metal vacuum structural material assembly welding of discharge quantity, level communicating pipe up and down, be located at the isolated tube in lower horizontal communicating pipe, the imbibition core, filling working medium in valve on the main body reaches forms through system vacuum seal, wherein the column comb is made up of the mild-steel sheet of 1～0.2mm, isolated tube is made up of the seamless carbon steel tube of 2～3.5mm, the imbibition core is to adopt electrochemistry, sintering, machining and the porous layer that is sprayed on the enhancing alveolation boiling heat transfer on the isolated tube outer surface, the filling weight of working medium accounts for internal volume below 10%.
Every group of radiator can be made up of 1～10 block of column comb.Isolated tube can be the independently part of heat pipe or another heat pipe, and it combines with main body and forms secondary and connect pressure change-vacuum-phase change radiator.Isolated tube also can be made up of the seamless steel pipe of two wall thickness 2～3.5mm arranged side by side.
The invention has the advantages that: adopted efficient heat transfer radiating principle such as phase transition of vacuum boiling alveolation, be provided with this special construction of isolated tube again dexterously, changed the routine that heating agent is directly flowed through and is full of the radiator internal volume.Be spaced inside and outside the radiator.The radiator internal pressure can manually be designed be controlled at certain scope that is higher than heating system pressure of being less than or equal to.Can select to press in the radiator ratio with heating system pressure in people's wish as transformer, make it to be operated in optimum range.Be spaced inside and outside the radiator, the general entrained corrosivity of heating agent, atmosphere is here thoroughly eliminated problems such as the oxidation of metal wall and calcium ions and magnesium ions foulings.The further thickness of attenuate radiator wall surface material reduces the weight savings steel consumption in view of the above, reduces thermal resistance and improves the thermal efficiency, and increasing the service life increases safety in utilization and its withstand voltage scope is expanded at double.
Another advantage is: range of application is wider.Be convenient to long-distance transmissions with heat, can adopt existing two-tube circulating vapour or water, the carbonated drink mixed transport also can be transmitted with the heat pipe-type single tube, even can transmit heat radiation with the normal air heat of compression that waste heat air or heat pump provide.Because this radiator internal volume often is under the vacuum state, the boiling point of internal working medium and freezing point are than much lower under the normal atmosphere pressure condition, there is not the problem of freezing spalling heat radiation wall in very a spot of in addition working medium, and is therefore freeze proof respond well, is specially adapted to extremely frigid zones and intermitting heating system.
Compared with the prior art the present invention can make change-vacuum-phase change radiator be convenient to can guarantee to fill the accuracy and the optimised quantity of working medium with high-vacuum apparatus batch production manufacturing, and high efficiency and safety in utilization are guaranteed in the acquisition of the internal volume high vacuum of guaranteeing to dispel the heat.
